XTRA II – Typical emission spectrum showing more than 40 dB ASE suppression.
XTRA II
High-Power, Single-Frequency Diode Laser
- Up to 500 mW @ 785 nm
- Typical linewidth <10 MHz (0.3 x 10-3 cm-1)
- ASE suppression > 40 dB
- Ideal source for Raman applications
- Fiber coupling available
The XTRA II provides three top features from one single unit: Gaussian beam profile, single-frequency operation and high output power. Incoherent ASE is suppressed by more than 40 dB, turning the XTRA II into the ideal choice for demanding Raman applications depending on a high signal-to-noise ratio. The integration of a high quality optical isolator as a standard feature ensures long term rock solid performance of the XTRA II.

Options
Fiber Option – FiberDock XTRA II
To provide full flexibility for OEM integrators, single-mode fiber-coupling is available on demand. Contrary to competing multimode lasers, the XTRA II achieves 250 mW output from a single-mode or even polarization-maintaining fiber. The fiber add-on consists of TOPTICA's patented FiberDock and an additional 35 dB optical isolator. Thus, highest coupling efficiency combined with best wavelength stability is guaranteed.Fiber output collimator – FiberOut
Some applications demand a fiber-coupled laser and beam collimation at the end of a fiber. To provide a comprehensive solution, the FiberOut turns the divergent beam at the fiber end into a collimated beam again (0.5 mm - 4 mm @ 1/e² CA: 4.8 mm). FC/APC connectors are standard, others can be accommodated. -
